Title: Improvements in or relating to the manufacture of a protein supplement for ruminant foods
IPC: A23K50/15
Filed: 1954-09-22
Abstract: Auto-condensation products of urea with biuret predominating are obtained by heating urea to between 120 DEG  and 205 DEG  C. Unconverted urea may be leached from the reaction product with a selective solvent such as water, methanol or ethanol and recovered for re-use as starting material.  The ammonia evolved during the heating step may also be used in the production of further quantities of urea starting material.ALSO:A protein supplement for ruminant feeds comprises one or more urea auto-condensation products obtained by heating urea at a temperature of 120 DEG  to 205 DEG C., in admixture with at least one other component of animal feed.  The crude auto-condensation products may be leached with a selective solvent for urea such as water to obtain a residue consisting of 60 per cent to 90 per cent of the auto-condensation products.  Preferred auto-condensation products are those in which biuret predominates and at least one member of the group consisting of triuret, tetrauret, pentauret, cyanuric acid, ammelid, ammonium cyanate and ammeline is also present.  The other animal feed component may be molasses, ammoniated molasses, ammoniated beet pulp, ammonium bicarbonate, ammonium lactate, urea, salt, protein cake (e.g. soybean oil meal cake), mineral mixtures (e.g. salt, ground limestone, steamed bone meal and a proprietary trace mineral premix), antibiotics, vitamins, hormones and/or extrogenic substances.  The products may be compressed or tabletted into cakes, blocks, tablets, rods or disks, with or without the addition of binding agents such as casein or other proteins, glues, waxes, resins, starches and fats.

Title: Process of drying seamless tubular bodies made of cellulose
IPC: F26B21/00
Filed: 1929-09-12
Abstract: 319,771. Kalle & Co. Akt.-Ges. Sept. 28, 1928, [Convention date]. Drying materials in long lengths. - Seamless tubular bodies made of cellulose are dried whilst they are inflated with air or an inert gas so that the dry tubular body has a greater width than the wet one. The tubular body may be treated with glycerine before drying if desired. In an example, a wet tubular body made by extrusion from viscose, the thickness of the walls of which is 0.2 m.m. and the diameter of which is 110 m.m., is passed through a solution of glycerine and then dried while inflating it under such a pressure that when dry the thickness of the walls of the tube is 0.032 m.m. and the diameter is 130 m.m. If the tube is then immersed in water it shows very little tendency to swell.

Title: Force measuring device
IPC: G01L1/12
Filed: 1957-09-04
Abstract: 819,010. Electric measuring systems. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 4, 1957 [Sept. 15, 1956], No. 27887/57. Class 40 (1). A force measuring device comprising a hollow iron shaft around which is wound an A.C. energized coil, and through the bore of which is linked a second coil connected to a measuring instrument, a signal being induced into the second coil by the distortion of magnetic flux consequent on the twisting of the shaft by the application of the force to be measured between levers attached at right angles to the shaft, is characterized in that the levers are bonded to flanges which are formed integral with the shaft, as by turning. In the prior art arrangement of Fig. 1, welds between the hollow shaft 1 and levers 5, 6, 7 distort the flux due to energized coils 11, 12, thus causing zero deflection of a meter 22 in the circuit of a pick-up coil 10, and lack of proportionality in its indication of the force applied, as when levers 5, 7 are fastened to the wire, and lever 6 to the hook, of a hoist. It is stated that these disadvantages are avoided in the device shown in Figs. 2, 3, in which the levers 5, 6, 7 are welded at 13 to flanges 2, 3, 4, integral with the shaft, and the pick-up coil 10 is linked through four holes in each flange. Rings 14 of magnetic material surround the windings 11, 12; if the flanges are of such size that the welds 13 are radially outward of the rings 14, the coil 10 need not be accommodated in holes in the flanges. The possibility of using a non-magnetic shaft is mentioned.

Abstract: 304,674. British Celanese, Ltd., Dreyfus, H., Kinsella, E., Bower, J., and Taylor, W. I. Oct. 24, 1927. Addition to 300,998. Apparatus for making filaments.-The cells for dry spinning artificial silk &c. described in the parent Specification may be modified in that they may contain an increased number of nozzles up to 100 or more, so that it is no longer necessary to partition the '' metiers " of the spinning plank into comparatively small cells. These cells and those of the parent Specification may further be open at the ends remote from the nozzles. In the form of apparatus shown in Figs. 1 and 2, each cell 1 contains two spinning nozzles 2 and a collector device 3. The bottom of each cell is open and the air drawn from the spinning room is heated, for instance by the coil 5 located inside the cell, and then led by the collector devices through the immediate vicinity of the nozzles 2 and drawn off by way of tube 6 through valves, constructions, or other regulating devices, with or without flow meters, as described in Specification 203,092. The filaments 11 are led through the open bottom of the cell to a godet 12 but may be led through openings in the wall of the cell. In the modification shown in Figs. 3 and 4, the cell contains a relatively large number of nozzles 2, each of which is provided with a collector device 14, 15. The evaporative medium is drawn off through the annular pipe 16 perforated on its under side. In Figs. 3 and 4 the bottom of the cell is open but in order to direct the incoming air in a substanitally vertical direction and to distribute the air evenly over the length of the cell, the bottom may be partly closed by a plate 20 leaving apertures 21, tubes 22 being inserted into the apertures, as shown in the bottom lefthand side of Fig. 4. The longitudinal walls of the cells may be provided with upwardly extending fins 23 to guide the air towards the collector devices. Heating may be effected by pipes 24 and the collector devices may be heated by pipes 25. In the apparatus shown in Fig. 5, each cell 26, the bottom of which is closed, accommodates 4 or other relatively high number of nozzles 2, the nozzles being arranged in pairs to form two rows along the length of the cell. The evaporative medium is drawn into the cell 26 through pipes 27 arranged along the length of the cell and controlled by valves 28 from trunk 29. The outlet from each collector device 31 may be separately controlled but it is convenient to connect the collector devices serving pairs of nozzles to a single draw off pipe 6. Downward extensions 33 may be provided to the collector devices and the relatively large chambers containing a large number of nozzles may be fitted with partitions, which extend for only a part of the total height of the chambers and separate off each spinning nozzle or small grouping of nozzles, such partitions being in effect merely extensions of the collector devices. Specifications 165,519 and 198,023 also are referred to.

Abstract: 418,047. Fire-extinguishing. KIDDE & CO., Inc., W., 60, West Street, Bloomfield, New Jersey, U.S.A. Oct. 13, 1933, No. 28328. Convention date, Nov. 10, 1932. [Class 47 (ii).] A fire-extinguishing installation comprises a container 1 for a medium, such as carbondioxide, under pressure, a piercer 7 for breaking the seal 5, a spring 14 for normally energizing the piercer, a detent 22 for restraining the piercer, and an actuator 45, sensitive both to heating and to the blast of an explosion for releasing the detent. The detent 22 consists of a rotatable spindle having a groove 23 engaged by a flange 24 on the cutter stem 10. The spindle 22 normally is held from rotation by a train of levers, the last of which, 27, is adapted to be moved, to release the spindle 22 and cutter, by a tappet 46 carried by a bellows member 37. The interior of the latter is connected by a pipe 44 to the actuator 45, which comprises a casing 47 closed by a diaphragm 50 which is supported against outward distortion by a perforated plate 52. Either a fire or an explosion in the neighbourhood of the actuator will cause an increase in pressure within the casing, which is transmitted to the bellows 37. The diaphragm 50 is retained in the position to which it is moved by an explosion by a catch arrangement 56, 57, for which a manual release 58 is provided. To prevent release of the carbon-dioxide by normal temperature changes, the bellows 37 is provided with a venting arrangement comprising a porous disc 63, for example of blotting paper. A manual release for the lever 27 is provided by a cord 72 attached to its spindle 70. A stop 16 secured to the upper end of the stem 10 is adapted both to limit the inward movement of the stem and to indicate, by its disappearance within a recess 28, that the stem has been released by actuation of the lever 27. The member 16 is shrouded by an opaque cap 29 with a transparent window. The medium in the container 1 may be released accidentally by fracture of the seal 5 due to excessive pressure in the container. If this occurs, some medium is passed, by passages 34, 35, 32, 36, to impinge upon the lever 27, thereby moving the lever 27 and, consequently, releasing the cutter stem 10. Consequently, the member 16 will indicate accidental, as well as automatic or manual, release of the medium. When the stem 10 descends, a cup leather 21 seals the passage 34 to prevent further escape of medium by the passage 36. Specifications 362,209 and 388,182 are referred to. The Specification as open to inspection under Sect. 91 describes also a form of actuator in which the retaining means 56, 57 is omitted. This subject-matter does not appear in the Specification as accepted.
